what exactly did you try? the advice was correct

/*/@from

or adding 
xmlns:t='urn:TMSWebServices' to your xsl:stylesheet  and using
/t:xtvt/@from
should both work.

I suspect that you confused yourself by calling
(this is the root element of the file...):
             ^^^^^^^^
the top level elemnt the root element, although that terminoligy is
sometimes used, it's best not to use it in xslt/xpath as xpath (1) a
root node is always the _parent_ of the top level element, not the
element itself. So there is never a "root element".
